HAME-TUG COUPLING. I

SPECIFICATION forming part of Letters Patent No. 376,305 dated January10, 1888.

(No model.)

To aZZ whom, it may concern.-

Be it known that I, DONALD HILL, a citizenof the United States ofAmerica, and a resident of Storm Lake, in the county of Buena Vista andState of Iowa, have invented an Imand combination of a clip adapted tobe per-.

inanently fixed to ahame, aTshaped knuckle, and two metal straps adaptedto be hinged to the knuckle and clip, as hereinafter set forth, pointedout in my claims, and illustrated in the accompanying drawings, in whichFigure 1 is a perspective view of one of the metal straps adapted to befixed to a hametug and detachably hinged to the knuckle. Fig. 2 is aperspective view of the knuckle adapted to be detachably hinged to theclip. Figs. 3and 4 are perspective vicwsof the clip adapted to be fixedto the ha'nic. Fig. 5 is a perspective view showing all the partscombined with a piece of a hame and a piece. of a heme-tug as requiredfor practical use.

a is a curved and perforated clip adapted to overlap the outside andconvex face of ahaine, and I) is a flat and perforated right-angledextension of the clip adapted to overlap the square and iron-bound edgeof the hame.

c c are perforated and parallelears projecting at right angles from theedges of the flat extension I). The complete device is preferably castin a mold and made complete in one piece of malleable iron;

1 dis a T-shaped metal kuuckle'adapted in size to be hinged between theparallel earscof the clip by means of a screw-bolt passed through theperforations in the ears and a bore, cl, in the knuckle.

V d is a rightangled and flat-sided extension from the central portionof the elongated knuckle.

g is a straight and perforated metal plate adapted to be riveted to thefront end of a. leather tug.

g is an integral curved and perforated end adapted to overlap theTshaped knuckle, as clearly shown in 5. A counterpart or mating plate, 9g, is placed on the opposite side, so they can'be jointly hinged to theknuckle by means of a screw-bolt, h.

The clip is fixed to the hanie by means of bolts or rivets, and theknuckle is hinged to the clip by means of a screw-bolt, h, in such amanner that the tug and plates 9 9' will have vertical play while theknuckle is stationary,

and the tug and plates and knuckle will have joint lateral play; but thetug will at all times be prevented from assuming atwisted positionrelative to the hame or a horse while in practical use, and by simplyturning the knuckle half-way round the tug can be lengthened andshortened at pleasure.

I claim as my invention- 1. A hame tug coupling comprising a metal clip,a, havinga flat part, b, and parallel extensions c c,'a T-shapedknuckle, d d, and

plates g g, substantially as shown and described, for the'purposesstated.

2. The combination ofthe metal clip a I), -having parallel ears 0, theTshaped knuckle dd, and two mating plates, 9 g, with a hame-tug and ahame, for the purposes stated.
